Asgard ADC on Breadboard

IMGP5316_s

Asgard on breadboard. Check the circuit diagram on our Github repo.

3rd August

Changed the sensor connectors to PCB, mechanical force at the joint was not good with the former socket.  The new socket is working fine, it’s a SIL through hole straight socket. We have notice of this variant being built and performing fine.


17th July

Assembly and test started, so far the sensors measurements are ok.

Pictures here.


13th July

The PCB arrived. It fits into the enclosure, that’s a good start :-). We will start the prototype assembly ASAP. 

 


17th June

3D printed parts arrived. They look fine, we will see if everything fits in well.

Also, a 3D printed AOA probe arrived.


3rd June

Sent out files for 3D print (click on name for online 3D model)

ASG-001 – Asgard – Base With Manifold – 03062017

ASG-002 – Asgard – Upper Enclosure – 03062017

Sent out printed circuit board for manufacturing


1st June 

We selected barbed fittings CN-M3-PK-2 by Festo for the pneumatic connections inside the ADC enclosure, we use silicon tube to connect with the sensors. Fittings look fine and will be tested prior to the enclosure case 3D print.

We are working on the PCB layout, no critical layout. The main requirement is that the soldering process should be really simple and necessary tools should be cheap and widespread available. It is possible to use Bluetooth modules from HC-05, HC-06, and BlueSmirf families.

 


13th May

The system for remote SD management is under test. It is alive.


Initializing SD card...initialization done.

11th May

We’ve received a very cheap HC-05 BT module. We will use it and eventually use it within the Asgard.


1st May

We’re experimenting with different possible layouts for the ADC. For this release, it should be lovely to leave to the user the possibility to select among two different Bluetooth modules. Dimensions are shrinking.


28th April 2017

Libraries renewed. Minimal working firmware code for ADC Asgard is ready. Test phase started. Here below you find ha video of a typical communication between ADC Asgard and a remote device via USB port.(comm strings here)


19th April 2017


18th April 2017

Breadboard finished. Tested SDCard, using standard libraries. Added temperature sensor and Bluetooth module. Each component was tested on its own. 


17th April 2017

Absolute and differential pressure sensor hookup. Note that booth pressure sensor provides also a temperature reading.


16th April 2017

First simple test of Teensy and Temperature sensor. The firmware used on this test has been published here.


10th April 2017

Teensy 3.6 with pins and temperature sensor TMP36GT9Z arrived from Watterott.com.


6th April 2017

 -=Awaiting for microcontroller Teensy 3.6=-
